Screw covers and bases may be used with flat head nails, countersunk woodscrews, self-tapping screws, rivets, drive screws, machine screws, washer faced screws and other types of fasteners. Can also be used with metric screws. Made of polypropylene with U.V. stabilized assorted colors. ‘Metallic’ colors also available. Cover options include: Screw Covers, Screw Bases, Hinged Screw Covers, Hex Dome Caps, Dome Caps & 3 Types of Socket Head Cap Screw Knobs.

Screw Covers These standard one-piece covers that pop over the screw drive. Works with screws from #4 to 1/4". Must be used with screw base.

Screw Bases These one-piece units are designed to set flush under the screw to give it a ‘colored’ outline. Use with pan and counter sunk headed screws from #4 to 1/4". Must be used with screw cover.

Socket Head Cap Screw Knobs We carry a full range of screw knobs to attach to socket head cap screws. You can alter the appearance or functionality of screws by attaching wing, round or flowerette thumb screw knobs, making them turnable without a socket driver.
